Application led may 15, 1908. Serial No. 432,959.

To all whom it may concern:l l

Be it known that I, GorTLIEB ROTH, a citizen of the United States, and a resident of the city of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Hog-Cleaning Machines, of which the following is a full, clear, and complete disclosure, reference being had to the accompan` ing drawings, forming apart of this spec' cation.,

This invention,v relates lto improvements in machines for removing dirt, hair, bristles and thelike from hogs or other animals.

The main object of my invention is to provide a strong, durable and comparatively simple and inexpensive machine that Awill lift the animal from a scalding vat, place Yit upon a conveyer, carry it into operative position to be cleaned, cleaut quickly and cleaning mechanism.

Other objects of this invention will appear in the following specification and claims.

In the accompanying drawings, Figure l is a side elevation of a machine constructed 1n accordance with this invention; Fig.2 is

a top plan view of the upper portion of the same; Fig. 3 a front'elevation of the same,

parts thereof being removed for clearness Fig. 4 a vertical section on line 4`-4 of Fig.' 3 but showing the machine at adifferentperio of its operation; Fig. a

elevation and a vertical tively, of one of the scraper elements; and Fig. 8is a side elevation partly in section of a detail of the machine.

Referring to lthe drawings the machine comprises a main frame consisting ofhorizontal base beams 1, vertical beams 2 resting upon said basebeamsand forming the four vertical outer corners of the main frame and spaced horizontal beams 3 rigidly secured between the vertical beams to hold position. This frame carries the main drive shaft 4 which extends chine, and is mounted upon bearings 4 fixed upon the oppositely disposed horizon- ,0 'tal beams 3' adjacent the upper end of the frame. The main drive shaft carries a main driving pulley 5 rigidly secured thereto and which is driven in theusualmanner from a countershaft or by any other suitable means. 5 An endless conveyer 6 comprising a plumain frame.

Aposed* lower horizontal cross thoroughly, and convey it away from the.

is provided in respectivel hrizontal section on line 55 of Fig. l; Figs. '6 and 7 are a sidev section, respec-' rality of sprocket chains 7 having spaced bars 8 secured thereto, is arranged beneath the main driving shaft. The conveyer chains 7 are carried by a series of sprockets 9, `upon a horizontal shaft 10, at the rear of the machine, mounted in bearings 11 which are vertically slidable upon the ways 12, which are rigid with the vertical beams 2 of the' main frame, and the chains also pass overfa similar series of sprockets 13, arranged upon a horizontal shaft'14 mounted in bearings 15 upon the front side of the veyer is depressed by means of a pair of idlers 16 which are arranged one upon each side of and over the conveyer and journaled upon the inner sides ofthe o positely disgars 3 of the main frame. The idlers 16 are provided with spaced recesses 17 around their peripheries, the distances between thespaces on the idlers being equal to the distances be- The upper side of the contween the' transverse bars ofthe conveyer,v

so that the bars fall in the spaces of the idlers as the conveyer is rotated. A heavy idler 18 bearings 19 which are verr upon the Ways 20, rigid with of the front vertical beams 2, of the main frame, to keep the conveyer c ains taut.

Mounted above `the conveyer and adjacent the depression in the upper surface thereof is tically slidable the front side a rotary scraper or cleaner 25 comprising a seriesof scraper elements or sections mounted upon a transverse'V horizontal shalt 26 journaled at its ends in the lower ends ci' a pair of arms'27, the u per ends of which are secured to the ends ci) a shaft 28 pivoted in bearings 28. rigidly mounted upon the inner surfaces of the `front vertical beams 2 of the main frame. Each section of the scraper comprises a hub 30 having radial arms 3l to each of which is secured a curved fiat spring plate' 32. Upon one side of each section Athe edges of the plates are substantially flush with one end and transversely of the maf of the hub, while u'pon the oposite side the edges of the plates project eyond Ythecorresponding end of the hub, (see Fig. 7). The hub is provided with a central bore adapted to fit upon the shaft 26 of the scraper and Witha set screw 33 to hold the hub ri idly in position. lThe several sections of t e scraper are arranged upon the sliaftmo 'brin the ends of the hub into contact and" to ring the ends oi the scraper lates 32 into a spiral arrangement, as shown in Fig. 3, the side edges ol' the plates upon each section overlapping the edges ofthe plates upon the adjoining section.

For driving the conveyer and for rotating the eleanera sprocket 25 is provided upon each end olI the main driving shaft 4, and a sprocket 36 is also rigidly secured upon each end oi' the conveyor shai't 10, at the rear of the machine, and a sprocket 37 is rigidly secured to each end of the cleaner shai't 26. A sprocket chain 38 upon each side oi' the mac ine communicates motion from each sprocket wheel 35 of the drive shaft to the Y corresponding sprocket wheels 36 and 37, oi

the conveyor and cleaner respectively, and a pair of idler sprockets 39 mounted upon an a'rm 40 pivoted between the idlers at 41, to the main frame, engaged upon opposite sides ol' each sprocket chain 38 to kee thcchain taut, the arm 4G being provi( ed with a weight 42 which tends to turn the arm upon its axis to tighten the chain. As shown in Fig. 1 each sprocket chain extends over the' sprocket 35 under the sprockets 36 and 37,

over the outer idler 3 9 and under. the inner idler 39,and thence returning to the sprocket 35.

v To raise and lower the bearings 11 carrying the .horizontal drive shaft 10 supporting the ,conveyer at the rear end of the machine, up-

wardly extending rods 45 one upon each si( e of the machine are pivotally secured at their lower ends to the ends of the drive shaft 10 and at their up er ends tocrank pins 46 adjustably carried3 by wheels 47 rotatably supported upon the ends of a transverse shaft 48 mounted in bearings 49 upon the rear side of` the main frame. Motion is communicated to the crank wheel 47 by means oi a gear wheel 50 u on the crank shaft 48, engaging a correspon ing )inion 51 loosely mounted upon the main rive shaft 4 and into or out of connection therewith by means oil a clutch 52 which is actuated by means of the shifter 53 pivoted to the bracket 54 rigid with the main frame and operated by cables 55.

To counterbalance the drive shaft 10 of the conveyor and the parts carried thereby a weightl is provided u on each side oi the machine carried by cab es 56 running over the pulleys 57 and 58, each cable being secured tothe corresponding bearing 11 of the said shaft 10. The cables 56 may also be attached respectively to the lower ends oi the arms ,27 carrying the scraper, as shown in Fig. 1, and also in detailin` Fig. 8 of the drawing to hold the rotary' scraper yieldingly in position. The connections between the cab es 56 and the arms 27 are preferably made adjustable, each cablr.` passing through an aperture 59 in the end ol its arm and being held gigidly in any desired position by means of a Cotter 6U which is threaded at its smaller' end and provided with a nut 6l,

whereby the Cotter may be drawn ti htly into engagement against the cable. hen the cables are thus connected to the arms 27, the downward movement of the rear portion of the conveyer will obviously cause an upward movement of tht` cleaner, and the u ward movement oi' the rear portion of t e conveyer will cause the cleaner to be moved downward by means of the downward movement of the weiUht. lf preferred, however, the connections zbetween thev cables and the arms may be omitted in which case the weight ol the scraper will be depended upon to hold the scraper yieldingly in position.

A scalding vat 65 is arranged upon the front side of the machine upon separate standards 66 mounted upon beams 67. If preferred, however, the vat might be rigidlysecured to the main frame of the machine.

To litt an animal from the scalding vat and put it upon the upper surface of the conveyer, there is provided a lifter 68 which is pivoted upon a shaft 69 to the upper inner edge of the vat. The free end of the lifter (i8 is curved upwardly as at 70, to keep the animal from` sliding o of the lifter when the lifter is being swun upwardly. Connecting rods 71 are pivota yrsecured at their up er ends to side extensions 73 of the lifter an at their upper ends to crank pins 74 adjustably carried by crank wheels 75, upon the ends of a crank shaft 76, which is journaled in bearings mounted upon the oppositely disposed transverse beams 3 of the main frame and is driven by means of a gear 77 rigid with the shaft engaging the hereinbefore mentioned pinion 51 which is controlled by the clutch 52 of the main driving shaft. The sealding vat 65 is provided upon its inner side with an inclined platform 78 which issubstantially in the plane of the inclined front u porportion 79 of the conveyor, and the li ter when in its uppermost osition is s ibstantially in alinement with t e said platf rm 78, and the said front upper portion of the said conveyer.

Tlieoperation of the machine is as followsz-When it is desired to start the machine power is ap lied to the main driving pulley 5 to rotate tr c main drive shaft 4. 1t` is evident that this rotation of the main driving shaft 4, which is in the direction indicated by the arrows, will cause a rotation of the conveyer and of the rotary cleaner in directions indicated by corresponding arrows.

When theparts of the machine are in the position shown in Iiig.` 1 of the drawing the clutch 52.is thrown into operation and the crank wheels 47 and 75 are thereby caused to rotate to move simultaneously the rods 45 and 71 to depress the rear portion of the conveycr and to depress the lifter 68 until these parts are brought into their lowermost positions, as shown in Fig. 4, the free end of the lifter being then adjacent andsuhstantially in alinement4 the rear sie,

with the bottom of the scalding vat. At this point in the operation of the machine the clutch 52 is thrown out of operation' until an animal has been rolled upon the lifter, from the bottom of the scalding vat When the clutch is again thrown into action whereupon portion of the conveyer and the lifter are simultaneously elevated and when the lifter is in its uppermost position'the clutch is disconnected and 'the animal slides downwardlyover the `inclined platform 78 and upon the upper inclined surface of the conveyer. The movement of thel conveyer continues during the rotation of the main drive shaft 4 without interruption, and the animal is brought downwardly intol the depression 'in thesurface of the conveyer and i y into position to be acted upon by the scraping plates or blades of the rotary cleaner which move in a direction opposite `to that of the adjoining surface of the conveyer, this difference in direction cansino the animal to be rotated so that all parts oiD the animal are subjected to the action of the scraper blades.

en, after having been subjected to the action of the Scrapers for a few seconds, the animal has been thoroughly cleaned, the clutch 52 is thrown into connection causing the rear portion ofthe conveyer to be lowered and the scraper to be elevated, thus permitting the animal to be carried by the conveyer past the scraper and to be delivered.

over the rear edge of the conveyer into a wagon or other rece tacle'which may be placed adjacent and elow the conveyer to receive it. Upon the delivery ofone animal from the conveyerthe machine is in position to lift a second animal from the scalding vat and to repeat the cleaning operation.
